Manic Miata fans out of action

Finally have the Miata back in Manic Mode for (hopefully) good. Seems to be running with all her former mania, but she has no cooling fans working.

I had the radiator out to do a timing belt / water pump, but it's all reinstalled and hooked up. I also removed the A/C compressor, condenser, and lines - not reinstalled, and won't be.

Tried the diagnostic jumper, and I think I hear the relay click when I push the throttle with ignition on, but no fans. With the car running, turning the A/C switch on lights the little blue light, but neither fan comes on. Car now has a Link-modified ECM, but the fans worked when it was in the car last year.

Other than the generic bad connection somewhere, is there any particular place I should look first?

Interested in what people suggest.
In mine the primary fan will come on only if I jump the connector, the AC fan will come on if the AC is going.

I'd start by checking that the fans actually work by applying 12v.

The blue light is triggered by the button, nothing more. Fun trick: if you take a non-AC Miata and pull the fan knob off, you can push the shaft in and turn in the AC light. Reinstall the knob and mess with the car owner.

Anyhow...is it running a full Link ECU? If so, check the settings as it can trigger the fan at different temps. What year is the car?

I thought this was going to be a thread about an injury in your cars fan club. I was thinking, wow, my cars don't have a fan club. Makes more sense, now that I see it is about cooling fans and not the other kind of fans.

I'll try direct power and see what happens. It was late when I fired the car up last night and I didn't really get too far into it. I just did the TEN-ground jumper in the diagnostic box and pushed the throttle down (key on). I thought I heard the click of the relay, but it might have been a mechanical noise from the linkage.

If I have removed the A/C compressor (and obviously disconnected it electrically) would the starboard fan come on when the A/C button is pushed? Or is the power feed for that fan in downstream of the compressor power switch?

I know I can jumper the starboard fan to the port fan and have them both come on together, but I was hoping to just use the stock A/C switch and wiring as an on-demand control for the second fan. It would be nice to turn it on and off, say while sitting in grid.

The car is a '96 running a full Obi-wan Link. I understand fan thresholds may be programmable via the pad, but I assumed the jumper trick would work regardless of ECU.

Thanks!

Ten/ground jumper is to set the timing on a stock ECU

Get the car warm to see if there is really a problem, and read the manual.

Huh. That TEN/GND thing was from Rod Grainger's manual. It was closer to hand than the FSM. My bad - guess I better dig that out.

I would still appreciate any light you can shed on the A/C switch fan control. Would that still work as I envision it, or do I need to extend power from where the compressor used to be over to that fan?
